利用阈值能量不可忽略的直接暗物质探测数据重建WIMP速度分布

Reconstructing the WIMP Velocity Distribution from Direct Dark Matter Detection Data with a Non-Negligible Threshold Energy

Chung-Lin Shan

摘要:

在本文中,我们调查的修改,我们的表达式开发的模型无关的数据分析程序的重建(时间平均)的银河系弱相互作用大质量粒子(WIMPs)的一维速度分布具有不可忽略的实验阈值能量。我们的数值模拟表明,对于高达O(200)km/s的最小可重建速度,我们对归一化常数估计量的模型无关修改可以提供精确的重建速度分布点,以匹配真实的WIMP速度分布,偏差<~ 10%。

英文摘要:

In this paper, we investigate the modification of our expressions developed for the model-independent data analysis procedure of the reconstruction of the (time-averaged) one-dimensional velocity distribution of Galactic Weakly Interacting Massive Particles (WIMPs) with a non-negligible experimental threshold energy. Our numerical simulations show that, for a minimal reconstructable velocity of as high as O(200) km/s, our model-independent modification of the estimator for the normalization constant could provide precise reconstructed velocity distribution points to match the true WIMP velocity distribution with a <~ 10% bias.
